Hi, sorry to bring this up again but all the previous threads on this topic have been archived.

I have had my Iridium Extreme set up with the Telstra plan and SIM with international roam on since 2018. I use the sat phone for emergencies so basically test before a remote trip and rarely use unless there’s an emergency.

Last week I found that I couldn’t received inbound calls on the Iridium.

Texts in and outbound and outbound calls are fine.

I saw ‘Suitcase’ in QLD had this issue back in 2019. Anyone found a solution /reason as to why this is a problem now? Was fine last check 12 months ago.

Also unable to send GEOS my location after several tests on the SOS button.

Thanks everyone !

I had the same problem, I was told the problem is if you get a new SIM that allows 5G then Telstra don't enable the sat options in their system. Even if it's the same number.

It was exactly as you described.

My solution was to rent SIM's by the week from here https://www.ozsatelliterentals.com.au/

The SIM rental is not on their website, but they do it for about $18 per week last time I checked. They post the SIM, and you post it back. Very flexible and friendly. Highly reccomended.

It is actually cheaper and incoming texts are free, not $4.00, so it works out well.

Thanks for your reply Tony.

I’ve had the same SIM card since 2018 and this issue has started in the past year so unlikely 5G related.

Unfortunately your suggestion won’t work for me as I live remote and take the Sat phone everywhere- I just rarely turn it on unless there’s an emergency.

The last time I used it was to call 000 as I came across a roll over on the highway with 5 people in the vehicle. No reception and very few people travelling past. It was important emergency services could call me back which atm seems to not be an option.

Hoping someone has had the same issue and has solved it previously.

Telstra (after suggesting I switch it off then on again)….ha ha … in their wisdom has suggested a new SIM card but I’m dubious about it……

Cheers

If you put the sim back in your phone, connect to your network and then turn off WIFI CALLING if it has been turned on, then put it in the satphone and try it, should be OK.
Update, Iphone cannot turn off wifi calling, its on by default, but if you put your sim in an android phone, turn off wifi calling you should be sweet, must be in phone range for it to work, its a network config change.
Also Telstra should be able to turn it off, if you can find someone there who knows what you are talking about.
